A low pressure system is building in Alaska which could mean snow for California. NOAA is currently forecasting that this low pressure system will drop down the West Coast of British Columbia, absorbing a weaker system and bringing snow to the Coast Mountains including Whistler Blackcomb on its way to California. Once in California, forecasters are calling for up to 12” of snowfall by the end of Tuesday.

Temperatures will be cold to start the week with well below freezing overnight low temperatures throughout the region.” – US National Weather Service Reno Nevada
